Myinvention relates to improvements in locks for doors and the likewherein a latch bolt, movable from a. normal door latching position to adoor releasing position, is pro- 5 vided with key actuated meansoperable from the outside and with manually operated means operable fromthe inside of the door independently of the key actuated means foractuating the latch, Vand also provided with lo manually operated meansoperable from the outside of the door for actuatingV the latchindependently of the key actuated means and the inside operating means,the key actuated means being movable to a locking position i5 preventingthe operating of the latch by either manual opera-ting means. i

The primary object of my present application is to provide an improvedlocking mechanism for doors.

Another object is to provide an improved locking device wherein' manualoperating means areprovided for operation frointhe inside and from theoutside of a door independently of a key actuated means operable 25 fromthe outside of a door for moving alatch to door releasingposition or forpreventing the operation of saidlatch. I Another object is to provideanVA improved device having an actuating member movable so in onedirection to operatefa door latch and in the opposite direction to-locksaid latch against movement.

A. further object is to provide an improved device of the characterdescribed which may 35 key applied fromthe outside of the door.

` Another object is to provide an improved device of the characterdescribed having man- 49 ually actuated operating means upon both theinside and outside of the door vandoperating independently of a keyactuated means operable from the outside of the door, saidkey actuatedmeans being operable to prevent opening of the 'door by either outer orinner manual operating means, and provided also with means operable fromthe inside ofthe doorto prevent operation of the outside manualoperating means. 5 Y

. A further Objectis to provide an improved be locked from the outsideagainst operation from either side by means other than a propermechanism which is simple and positive in its actionY and whichmay beeasily assembled andinstalled. Y Y

'p Referring kto the drawings, the numeral- 1 is Vused to designatelingeneral a door having a latch bolt 2 slidably mounted within a casing 3set within yan opening 4 formed in the edge of the door. The bolt 2isnormally held in latching position by al spring and is provided with aU-shaper eXtensionG'eX- manner in which the latch bolt is engaged by ofthe tending-axially into the opening 4 and yguided i at its inner end bya reduced portion 7 of the casing 3,'said eXte'nsi-onfbeing providedwith .a yokey shaped vend 8 having spaced transfv versebar portions Satthe inner. end ofthe extension 6. i f An opening 9 is formedtransversely through thedoor to intersect `the opening 4, and a recessllis formed upon thev inner side of the door. A cylinder lock 12 of anysuitable constructiomjsuch as commonly known,

is secured withinthe opening 9, preierably by means of a plate la'daptedto seat against the 'back 'of -there'cess J11 and to be secured thereinby kscrews 14. The lockis provided with the usual outeriange 16 seatingagainst a face plate 17 mounted1 upon the outer face of the door 1. Thelock 12 is provided with the usual rotatable cylinder mounted within acasing and adapted to be operated by a suitable key in the ordinary .andwell known manner.

A post 21 is mounted upon the inner end of the lock 12in inwardlydisposed axial relation to the cylinder of the lock, said postpreferably being mounted by means of a mounting plate 22 secured uponthe inner end of the lock cylinder by means of .screws 23 and having acentral opening through which the post 21 extends. A flange 24 formedupon the end of the post 21 is engaged between the plate 22 and theinner end of the lock cylinder.

,Arlatch actuating Ymember 26 is rotatably mounted' upon the post 21adjacent theouter face of the plate 22.v The member 26 ,has an arcuateslot 27 formed therein and engaged by a pin 28 carried by the plate 22,the pin 28 preferably being formed as anv extension upon the head of oneof the screws 23. The member 26 is provided with a latch engaging arm 29adapted to extend into engagement with the U-shaped extension 6 of thelatch bolt 2 and to engage the lowerbar portion .8" thereof asbest shownin Fig. 2 of the drawings whereby ,a rotationof the lock cylinder andthe plate 22 in a clockwise direction as viewed from the `outer, side ofthe door will cause said arm 29 to engage and move the latch bolt to adoor releasing position, as indicated in dotted lines. y i

. Q The member 26 is also providedwit'h an actuating arm 31Yhaving aroller 32v mounted Y thereon, said arm'and roller being adapted to beengaged by the upper end of a plunger 33 slidably mo-unted within therecess 11 and guided by means of a guide plate 34 secured upon the plate13, preferably by the screws 14 which serve to secure said plate and thelock 12 .upon the door. A transverse extension 36 is `formed upon thelower end of the plunger `33. Alatch lever 37 is pivotally mounted uponthe face plate 17 and arranged tovextend inwardly through openings 38and 39 formed in said plate and the door respectively into engagementwith the 'under side offthe transversek extension 36 whereby a downwardmovement of the outer end of the latch lever 37 Ywill cause the plungerto be raised against the ressure of a s rin Y 41 to engage and move thearm 31 and *thereby actuate the member 2 6 to operate the latch asindicated in dotted lines in Fig. 2.

The guide 34 is arranged to-permit a lmited transverse movement of theplunger 33 therein, said plunger normally being` held in. valinem'entwith the roller32 by means of a suitable leaf spring 42.l The upper endof' theplunger is inclined as at 43wherebyV a downward pressure of theroller 32 upon the end vof ytheplunger will operate to press the endofthe plungervtransversely outof alinebar portion 8.

`ranged to be received within a ment with said rollerv ,and permit theroller and arm to be moved past the plunger and into an inoperativerelation thereto for a purpose hereinafter more fully explained.

The member 26 is provided with a stop 44 adapted to be moved into thepath of the yoke 8 of the latch bolt extension 6, as shown in Fig. 4 ofthe drawings. The stop 44 is so spaced from the arm 29 that said stop ismoved under the upper bar portion 8 and between the side ofthe yoke 8when the member 26 is moved to actuate the latch. When the plate 22 isturned in the opposite direction by turning the lock cylinder in acounterclockwise direction by means of its key, the pin 28 ismovedthrough the slot 27 to engage the opposite end of said slot andthereafter to move the member 26 to a locking position as indicated inFig. `4,.thereby causing the arm 29Yto be moved between the sides` ofthe yoke 8 and causing the stop 44 to be positioned within the path ofthe upper y As the member- 26 is thus moved, the actuating arm 31 ismoved to displace the plunger 33 laterally and to be moved past saidplunger as above explained whereby the plunger' isrendered inoperativeas a means for actuating the member 26.

A second latch actuating member' or cam 46 is mounted upon the post 21adjacent the mcmber26 and rotatable on said post independently of themember 26. The member 46 is provided with arms 47 extending into theyoke 8 and adapted to engage the bar portions 8 as best shown in Fig. 5of the drawings, whereby a turning of the member 46 in either directionwill c ause the latch to be moved to a Adoor releasing, position. 'Themember 46 is provided with a socket 48 arranged axially with respect tothe post 21 and having its open end disposed toward the inner side ofthe door. A flange v49 formed upon the end of the post 21 holds themember 46 in operative assembled relation to the post 21. A suitabledoor knob 51 is mounted upon the inner side of the door 1. Therknob 5lis provided with a stem 52, preferably square in cross section,extending into engagement with the open end of the socket 48. A bushing53 is mounted upon the stem 52 and arbearing 54 secured upon the innerside of the door. A collar 56 secured upon the stem 52 adjacent theinner edge of the bearing 53 serves to hold the knob and stem inoperative position upon the door.

A locking member 57 provided with an operating knob 58 is slidablymounted within the door and arranged to engage a notch 59 formed in theside of the plunger The member 57 is arranged to be operated from theinner side of the door andis provided with a notch 61 normallypositioned to permit free movement of the plunger to actuate the member26. By moving the member 57 outwardly through the inner face of thedoor, the notch 61 is moved out of alinement with the plunger 33, andthe member 57` is moved into engagement with the notch 59 as shown inFig. 6 thereby etectually locking said plunger against verticalmovement. The member 57 engages the plunger 33 upon the side oppositethe spring 42 so as not to interfere `with the transverse movement ofthe plunger;

Vhen it is desiredto lock the door from the outside, a proper key isinserted into the lock 12` and turned inl a counter-clockwise`direction. As the cylinder of the lock and the plate 22 are thusturned, the pin 28 lirst moves along theslot 27 until the opposite endofsaid slotis engaged and thereafter the member 26 is turned tosubstantially the position indicated in Fig. 4 of the drawings. At thesame time, the arm 3l is pressed against the upper inclined face of theplunger 22, said plunger being displaced against the pressure of thesprings 4l and 42 until the roller passes said plunger. Toremove the keyfrom the lock it is of course necessary to turn the key back to normalposition. As the key is turned back to normal position, the pin 28 movesback along the slot 27 to the position indicated in dotted lines inFigf4 and engaging the end of the slot to form a stop Yoperating toprevent rotation of the member 26 in a counter-clockwise direction. Y gL In this position, the stop 44 is disposed immediately in back of theupper bar portion 8 so that any-inward movement of the latch bolt 2willr causesaid bar portion to strike against the stop 44 and-preventthe movement of the latch'to its door releasing `position. The plunger33 may be'freely operated past the arm 31 and roller 32 withoutimparting any movement to the member 26, thus preventing the latch frombeing operated by the lever 37, andthe latch is effectually lockedagainst operation by means other than a proper key applied and operatedfrom the outside of the door. Y I

In operation, my improved locking mech anism is constructed andinstalled-substantially as shown and above described. yWhen the member26 is in normalroperativev position, the latch bolt 2'may beoperatedmanually from the outside by pressin the latch lever 37downwardly and thereby li ting lthe plunger 33 against the arm 31 androller`32 wherebythe member 26 is turned and the arm 29 moved to engageand actuate the latch bolt.

rl`he latch bolt may also be operated from the outside by inserting akproper key into the cylinder lock 12 and turning said keyfand the lockcylinder in a clockwise direction,` thereby causing the pin 28`to bemoved tothe end of the slot 27 and then to Koperate the member 26 whichin turn actuates the latch. The latch is operated from the inside of thedoor by turning the knob 51 in either direction. The slot 27 normallypermits the memthe member 26.' rIhe blocking of the plungerk 33 howeverdoes not interfere lwith the movement of the member 26 independently ofsaid plunger and the latch may be operated by a proper key as abovedescribed.

I To move the member 26 from its locking to its normal position, thelock cylinder' is turned lby its key in a clockwise direction. Themember 26 is turned by the pin 28 and the arm 3l and roller 32 forcedagainst the side-of the plunger 33 until said plungeris pressedlaterally against the pressure of the spring 42 suiiiciently to permitsaid roller to pass the plunger and move into .alinement with the end ofsaid plunger. At the same time the stop 44 is moved'out of the path ofthe yoke portion 8 and the arm 29 is moved to operative positionadjacent the lower bar portion 8 whereby a further turningvof the keywill cause the latchto be actuated as above' described.

The specific details of construction of Lmy improved door lock asillustrated and described may of course be modiiied in a number of Wayswithout departing from the spirit of my invention. I therefore desire toavail myself of all such modifications as may fall within the scope-ofthe appended claims.
